sbt supress ignoring option MaxPermSize=256m

PS D:\Users\erick\repos\leaderboard> sbt about

The Java Development Kit (JDK) installation you have is not up to date.
sbt requires at least version 6+, you have
version 0

Please go to http://www.oracle.com/technetwork/java/javase/downloads/ and download
a valid JDK and install before running sbt.

Been searching for almost an hour for some way to suppress

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0

in SBT, but it seems impossible. Is there some way to do this?

This Solution worked for me

  1. Go to project directory
  2. Open directory sbt-dist\conf
  3. Open sbtconfig.txt file and comment below property by putting # prior the line #-XX:MaxPermSize=256m

There are many solution which show downgrade to java version. You don't need to do just follow above steps . It will work.

As usual, I seem to find the solutions shortly after posting the problem:

  1. Go to SBT installation directory
  2. edit conf/sbtconfig.txt
  3. remove -XX:MaxPermSize=256m

Sadly, Google provides many sbt hits that are either wrong or out of date, so it takes a while to find valid solutions.
